The Schedule referred to in these Letters Patent and making part of the sanne.

fo all whom #it may concern I drawing and te' the-letters of reference marked thereon.

This invention relates to machines for cutting straw, hay and similar feed material; and V The nature of this improvement consists'chietly iu the .arrangement lof aneccentric cutter-knife tothe arms of a fly-u'heehand to the peculiar combination of levers, ratchet devices, and feed-rollers arranged adjustably. to regulate the -feed-motion of the stuff to be cut, hereinafterto be. morefully described.

To enable those herein skilled to make Aand use `my said improved invention, I will now more fully describe the same, referring to' Figure 1` as a side elevation; to

Figure 2 as a front elevation; to

Figure 3`as a top plan; and'to Figure 4 as a part sectional elevation at line :c y.

The trough A, of the usual material and constructive form, and operating machinery, is mounted uponv a properly constructed frame, B. A

The material to be cutis entered in said trough, and is fed to the cutting-point by the -action of the feed-rollers C O'.

At its end the trough A has a metallic bottom and face-edge a, the latter to resist the dash of' the cutterknife. Y

The fly or balance-'whecl-D, constructed of the required size and weight, to Icounteract any irregulari-v ties of motion on part 'of' the feed devices', is supported on'the shaftE, which rests in proper journal bearings on the frame B', close to the side of the trough A On the projecting arms. wl, of the fly-wheel D,l .have arranged the cutter-knife F of such circular construction, t-hat'the same shall form an eccentric relative tothe shaft E, and which, in'itsr :cutting-action,

shall have a drawing cut, entering the stuff' gradually, without shock or jar.

rBhe constructive form of said cutter is plainly shown in fig. f2.

i The feather or'sprng lever 1*",pi-voted at b to the frame B, and properly secured to the end of the shaft E, `I arrange so that, by its springing action, the cutter-knife is caused to rotate so as to cut against or close up to the face of' the plate a, of the trough, and in passing clear it freely.

trough.

The Iconstruction audaction of the feed devices are as follows:

On theshaft E I secure aca1n,fe, to rotate within the slotted overhanging lever arm. G, pivoted at g `to the main lever H, which, in its turn, has its fu'lcrnm at h o n rthe frame Said lever H has its movements guided within thef slotted vertical guide H', also secured to the frame B, and is regulated by the set-screw h'. f

To said lever H I also attach the ratchet-pand I, constructed so as to .impel the movements of' the ratchet-wheel'J, secured ,to the lou-er shaftc,a1id about which the lower feedfroller O revolves.

Said shaft c has its journals resting iu proper bearings secured to the bottom of the trough sides A.

l `urthermore, I attach to the sides of the hopper or trough A the bell-crank lever K, having its arms respectively pivotcd with the cam-arm G at L', and at It', in connection with theratchetdever L, engaging in the teeth 'of the upper ratchet-Wheel M, secured to the 'shaftc'. Said shaft carries with it the upper feed-` roller C'.

The eccentric-action of the cam c gives a reciprocating motion to the respective levers, which in their turnoperate 'the' pawl-and-ratchet devices, and thus impart to cach roller that ,intermittent rotary action required to feed forward thestraw 0r stuff preparatory to the cutting `aetipn of tlleknife.

Areturn movement on the part of the ratchet-wheels is prevented by the arrangement of the parvis 'i i' sec ured to the trough and frame, respectively, as shown in fig. 1. p I

The feedrollers C C I construct of cast-iron, having theirdent-ire'circumferential faces corrugated with depressions, and forming V-shaped ridges, as shown in figs. 3'and 4. Byt-his means the feed material is very readily and perfectlyfed to the cutter-edge.

To allow, however, for more or less material to be fed between said rollers, I have arranged the shaft c (carrying the upper roller) to operate adjnstably in proper slots on each side of' the hopper A, and support the journals of said shaft in the projecting bearings a ofthe sliding standard N, which passes vertlcally down each side of the trough A, having its bottom piece connect-ingk with a spring bar, O, which has its curved end attached at o to the bottom of the It is evident that the tension of the spring bar Q and its connection with vthe sliding standard forces down the journals of the upper roller C', and-thus the stuff between the rollers, being under pressure, is carried forward as require( The journals of each roller are sufficiently protected by the' trough bom-ds, as at a, and also in front ofsziid rollers, the metallic plate a' hung loosely in the side bearings, prevent any clogging` action of the feed in its `Gr,pivoted and connected to angle-lever K, lever H,

guide H', set-screw h', ratchet devices L l J M, pnwls e' fi', corrugated feed-roller C C', platen', sliding standard M, sp1-ing bar O, when all snid parts are combined and constructed to operate substantially in themen-- ner and forthe purpose described. I

In testimony of sa-id invention I havev hereunto set my band in presence of- H RISTOPH .'KEMPER.
